[BTW, I meant C-r, not C-s. My brain can never recall why my fingers type.]

M-r seems to be a step in the right direction. However, you don't know what command line it will grab until after you press <RET>. As an example, I just tried  "M-r cd<RET>". It found a command with "CD" in the middle of it. I wanted the one that started with "cd".

With xemacs, "cd M-p" would have found the most recent occurrence of a command that started with "cd", and entered it as the current command so I can edit it (it doesn't take you to the location in *shell* of the match like C-r does). No need to press <RET> first and hope it grabs the right one. Also, each time I type M-p after that, it will grab an even older instance of a command that starts with those same chars. So I just type the first few chars of the command, and then type M-p until xemacs finds the one I want.
